A LumenoCity-style event might be coming to Cincinnati Union Terminal the first weekend in September.

A new LumenoCity-like light show might be coming to Union Terminal during the first weekend in September.

The event hasn't been finalized yet, but the Cincinnati Museum Center and creative partner Landor are working on details.

"We would so like to make this happen," said Elizabeth Pierce, vice president for marketing and communications at Museum Center.

The Cincinnati Symphony Orchestra, which is producing August's LumenoCity in Washington Park, is not involved in the Union Terminal plans.

This new event would play up Union Terminal's connection to the Hall of Justice. The Hall of Justice is the fictional headquarters of the Justice League comic characters and was modeled after Union Terminal.

"If we could pull it together, it would be such a spectacular experience," Pierce said.

Financing the event is the biggest issue for now.

Last year's LumenoCity, performed with Music Hall as the background, was estimated to cost $1 million. The Union Terminal event would cost at least $500,000, Pierce said.

There are logistical questions, too. How would people access the event? Would it be drive-in style? A combination of people and cars?

The first LumenoCity drew unexpectedly large crowds to Washington Park. The 2014 event, Aug. 1-3, is a free but ticketed event for 37,500 people – 12,500 each night. Tickets were distributed to CSO and Cincinnati Pops subscribers, with the remaining "selling out" on Ticketmaster in 12 minutes Monday morning.
